The shaft-9 has keyed to i t.a gear 10. (Shownin dottedlinesiinFigs. 2a d3 "The gear 10 is connected through .suitable system ofgears (not hei-eshown) with llietyvo indicator-pointers 1l and l,2-, moving, respe over gnaduationsv.13` and114. 'l ''i The .relations ofthe-circumference ofthey traverse-wheel to that of its path on thebledfl on' which it travels' and the,A gearing between 10: the traverse- Wheel and f indicator and the gearing in the indicator are such that the .17o v Fig. 3 isa plan showing afportionfof'- lthe bed on which the traverse-wheel'rest-sandr pointer 11 revolves once per revolution of the carriage, having the same angular rotation as the carriage at all points, so that the grad uation pointed out by thisd needle shows the exact revolution of the carriage in degrees. The relations of the gears in the indicator itself are sucht-hat the needle 12 makes one complete revolution for each degree passed over by the needle 1l. These' two needles thus show the exact position of the carriages 'in degrees, minutes, and fractions of min u tes.

The carriage should have some fixed zero point atwhch both needles are set exactly at zero, and the indicator should have means to facilitate this adjustment. A suitable indicator-having these several functions is described and claimed in my application filed November 1, i900, Serial No. 35,133, of which Lin this case is a division.

Shaft 3 has a tightly-fitting roller bearing'.

in the load-beam Rotation of the traverse. wheel causes the load-beam to move, which in turn moves the carriage by reason of the twovertical doWel-pins 15, screwed through.

against collars 21 and 22, secured to the bottom of the load-beam. Through these collars the pressure on the springs is put on the loadlbeam,fby which it is transmitted to shaft 3,

and thus mainly to the traverse-Wheel, causing it to bear on the bed with sufficient pressure to prevent 'slipping when it is rotated, as should slipping occurthe traverse-indicator will not show the true angular position of. the carriage. In any style of carriage Where' theseprovisions against slipping are insufficient aseparate wheel may be provided to roll on the bed or some other stationary part of the carriage and then have the indicator mechanism geared to'it instead of to the traverse wheel vor mechanism.

Shaft 3 should be suitably secured aga-inst longitudinal motion. It carries a ring 23 against a shoulder near its outer end. Between this ring and the bottom of the recess in the hub of the Wheel 4 may be placed thin rings or plates to carefully adjust the distance of the traverse-wheel from the center of the carriage, so that one revolution of the carriage will give exactly one revolution of the indicator-needle 11.

' `Shafts 9 9a are usually driven by cranksy -placed on a shaft 24, driving a pinion 25,

gearedto awheel 26, (shown in dotted lines in Figs. 2 and 3,) keyed to the shaft 9, and throughthe latter and its pinion 8 driving the geared Wheel 7, mounted on the traversewheel. lf the crank used to operate shaft-"9 be placed on the shaft 27, it may be made to 7o drive the gear l() through the pinion 28, keyed to saidshaft 27, and thus move the carriage with still greater force, ease, and steadiness, enabling a single man standing directly in Y front of the indicator to traverse the carriage and observe its exact movements and position through the indicator.'

Should there be troublein observing the true position ofthe carriage, owing to slipping of traversewheel 4, an independent wheel 8o may be geared to the indicator and operated by the motion of the carriage over the bed,- the traverse- Wheel in this case having no direct connection with the indicator. Such a c ase would be shown by the present drawings Were the wheel -to cease to be the traversewheel. In such use shafts 9a, 24, and 27, with their pinions 8a, 25, and 2S, would be removed. i The wheel 4 would no longer constitute the traverse-wheel of the carriage, but through 9o the pinion 8, shaft 9, and gear 10 would, as* before, operate the indicator,vvhich, moving -with the greatest ease, would not ca-use the Wheel 4 toslip, and in this case the Wheeland the indicator would move in entire'harmony 95 with the carriage. Of Acourse Were this done another traverseewheel placed .elsewhere or other means would have to be providedto traverse the carriage. f

I have shown and described certain patent- 10o able features of a gun-carriage in disclosing the nature and objects of my present invention; but I do not claim these features in this case, for .the reason t at they` are already claimed in my copendlng applicationv o riginally filed April 13, 1893, renewed November 22, 1893, Serial No. 491,686. v

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

. I IO l.` In .combination with a gun-,carriage and afixed bed over which the carriage has an;
